Introduction: Surgery for inguinal hernia is often linked with substantial postoperative pain and discomfort and is a frequently performed surgical intervention. The use of local anesthetic infiltration has been found to enhance the management of postoperative pain, decrease discomfort, minimize nausea and vomiting, reduce respiratory issues, and lower the need for opioid medications. This research aimed to compare the effectiveness, duration, and adverse effects of transversusabdominis block versus ilioinguinal nerve block in the context of postoperative analgesia for inguinal hernia surgery. Methods: This observational study involved patients aged between 20 and 50 years who were randomly divided into two groups of 30 individuals each: Group T received a Transverse Abdominis Block, while Group I received an Ilioinguinal Nerve Block. The study protocol included preoperative assessments, standard diagnostic evaluations, and administration of anesthesia according to the assigned group. Continuous monitoring of vital signs, pain levels, and postoperative complications was carried out. Statistical analysis was performed using MS Excel and SPSS version 22, utilizing appropriate statistical tests and graphical representation of data, with a significance threshold set at p < 0.05. Results: No significant differences were observed in age, sex distribution, weight, visual analog scale (VAS) scores, adverse effects, or mean time to rescue analgesia between the two groups. Both techniques were deemed safe and effective for managing postoperative pain. The quality and duration of pain relief achieved with the transverse abdominis plane block were comparable to those with the ilioinguinal nerve block. Furthermore, the occurrence and severity of side effects associated with both nerve blocks were minimal. Conclusion: The study findings suggest that both methods are equally safe and effective in alleviating postoperative pain. Both transverse abdominis plane block and ilioinguinal nerve block are viable options for improving postoperative analgesia outcomes in patients undergoing inguinal hernia surgeries.
